DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a laminator material pressurizing apparatus and method according to the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, A is a laminator used as a laminator B for laminating a coating sheet described later on the surface of a base material b made of a bar-shaped material such as a flat material, a construction material or a thin material. Material pressurizing device, comprising a transfer means 1, a support 2, a rotating means 3, and a passive member 4.
, The cover 5, the air supply means 6, the press roller 7, and the heating means 8.

As shown in FIG. 3, the laminator B comprises a coating sheet c, a coating means 10, and a drying means 11
And a sticking means, that is, a material pressing device A.

Among them, the above-mentioned covering sheet c is formed by using a long sheet having a predetermined width, which is supported by the holding means 13 so as to be able to be extended to the body 12, in a roll shape.
For example, non-woven fabrics formed of polyester, rayon, acetate, glass fiber, etc., PVC sheets, printed paper,
What consists of a dup sheet, a phenol sheet, a melamine sheet, etc. is adopted.

The coating means 10 is for applying an adhesive to one side of the cover sheet c adjacent to the holding means 13 for the roll-shaped cover sheet c.
Depending on the material of the cover sheet c, hot melt, vinyl acetate, a solvent type, or the like is used and housed in a glue tank (not shown), and a predetermined application is performed by passing the cover sheet c.

The above-mentioned drying means 11 dries the applied adhesive of the coated sheet c in a predetermined manner, and
Is heated to a predetermined temperature at which sticking to the substrate d is good.

The drying frame 14 has a structure in which a transfer path for moving the coating sheet c of a predetermined length from one side to the other side is formed in series with the coating means 10, A heating means 15 connected to the inside of the body 14 to heat the inside; an air supply means 16 facing the inside of the drying frame 14 and linked to the heating means 15 to feed it to the drying frame 14; An exhaust port 17 that is opened at one or a plurality of locations in the body 14; a heat-dissipating cover 18 that is openably and closably attached to the exhaust port 17;
An operation means 19 for selectively closing and opening 8 and an exhaust means 20 connected to the inside of the drying frame 14 for discharging hot air from the drying frame 14.

In the laminator material pressurizing apparatus A according to the embodiment of the present invention, the transfer means 1 is provided on the body 12 such that the transfer surface thereof is substantially horizontal to force the base material d in one direction. At least a surface portion thereof is formed of an elastic material such as rubber, and uses rollers driven by a driving member 21. A plurality of rollers are arranged at a predetermined pitch.

The above-mentioned support 2 is supported by a holding member 22 provided on the body 12 above the transfer means 1, and supports a later-described pressing roller 7 in a horizontal direction and a vertical direction, and furthermore, rotatably. .

The holding member 22 is connected to the transfer means 1.
Is mounted on a body 12 such as a pillar standing upright in front of and behind the vehicle by a vertically moving member 23 composed of a vertical screw shaft and a handle.

The moving member 2 is slidably movable to the holding member 22 by a moving member 24 including a horizontal screw shaft and a handle.
5 is attached to the movable body 25, and a mounting member 27 which is rotatable by a rotating member 26 composed of a worm and a worm wheel is provided.
Is fixed.

Accordingly, the pressing roller 7 can be brought into contact with the material at an arbitrary position and at an arbitrary angle by the lifting member 23, the moving member 24, and the rotating member 26. The building material can be similarly laminated at an arbitrary angle not only on the top surface of the material but also on corners and side surfaces.

The rotary shaft 3 is rotatably supported on the support 2 so as to be in a lateral state, that is, substantially parallel to the material transfer surface.

The above-mentioned passive member 4 is fixed to one end of the rotating shaft 3 and applies a rotating force to the rotating shaft 3 in one direction by an air supply means 6 described later. A plurality of blades 29 are attached to one side surface of the passive member 4 so that a predetermined space is formed on the outer peripheral portion of the passive member 4, and the wind blowing of the air feeding means 6 acts efficiently. Is surrounded by a cover 5.

The above-described air supply means 6 is connected to the inside of the cover 5 to apply a rotational force to the passive member 4, and uses a conventional blower, and the hose 30 connected to the discharge port thereof is used. Is connected to the inlet 31 of the cover 5, and the rotary shaft 3, that is, the pressing roller 7 is rotated via the passive member 4 by the pneumatic pressure fed into the cover 5.

The air supply means 6 can also be used in combination by branching the air supply hose of the air supply means 16 used in the drying means 11 described above.

The pressing roller 7 comes into contact with the surface of the material formed by the covering sheet c and the base material d which are fixedly attached to the other end of the rotating shaft 3, and the transferring means 1 presses the material by a predetermined pressure. A rubber roller or the like having predetermined elasticity is used for clamping.

The driving force of the pressing roller 7 by the air feeding means 6 is set to a driving force lower than the material transferring force. That is, an abnormal resistance is applied to the material feeding of the transferring means 1 by the driving member 21. When the transfer means 1 stops, for example, when the transfer means 1 stops, the pressing roller 7 in contact with the material sets the air pressure of the air feeding means 6 to the strength at which the rotation of the rotary shaft 3 stops as the material stops. As a result, the material is not caught or forcedly transferred, and the material is not damaged.

The rotational force which does not affect the transfer force of the material by the transfer means 1 is not shown in FIG.
If a clutch means such as a torque limiter is attached to the joint between the pressing roller 7 and the pressing roller 7, when a constant rotational load is applied to the rotating shaft 3 during feeding of the material, the driving force is avoided to prevent the pressing roller 7 from moving. By stopping the rotation, the above-mentioned purpose can be achieved.

The heating means 8 heats the peripheral surface of the pressing roller 7 in correspondence with the pressing roller 7, and uses a conventional heater or the like, and is rotated by the air feeding means 6. Since uniform heating is applied to the peripheral surface of the pressing roller 7, the temperature of the material surface, in particular, the surface of the coated sheet c to be heated and transferred is reduced by pressing with the cooled roller. Without reheating, and
The applied adhesive is softened to promote activation.

One example of this configuration is that a cover 33 covering substantially half of the outer periphery is attached to the support 2 above the pressing roller 7 supported by the rotating shaft 3, and the upper part of the cover 33 is removed. By connecting the inlet pipe 34 and the discharge side of the heating means 8 and connecting the branch hose 35 of the air supply means 6 to the receiving side of the heating means 8, the heating means 8 The generated heat source is pressure-fed into the cover body 33 by the air feeding means 6 to heat the pressing roller 7 in a predetermined manner.

If the heating means 8 always provides stable heating to the pressing roller 7 without using a cover, the cover 33 need not be provided. Is preferably provided with the cover body 33.

In the laminator material pressurizing apparatus A according to the present invention configured as described above, the roll-shaped covering sheet c supported in advance by the holding means 13 of the machine body 12 is pulled out at its end and dried. It is inserted into the means 11 and moves toward the material pressing device A, and an adhesive is applied to one side of the cover sheet c during the transfer.

The covering sheet c is superimposed on the upper surface of the base material d supplied from one side of the machine body 12 and moves while being strongly pressed by the roller-shaped transfer means 1 and the pressing roller 36 thereon. Further, a predetermined sticking process is performed by the pressing roller 7.

At this time, the pressing roller 7 is rotated at a predetermined speed in one direction, that is, in the material feeding direction by the rotating shaft 3 rotated by the air feeding means 6 via the passive member 29. Further, the material contact surface of the pressing roller 7 is heated to a predetermined temperature by the heating means 8 and the air sending means 6, for example, about 40 ° C. to 70 ° C. depending on laminating conditions.

Therefore, even before the material arrives, the peripheral surface of the pressing roller 7 is uniformly and uniformly heated, so that the temperature may be reduced on each surface which comes into contact with the supply of the material. Instead, the cover sheet c softens to a desired state, and the cover sheet c conforms to the outer shape of the substrate d.

The height with respect to the surface of the material is adjusted so as to obtain a predetermined pressing force. When the transfer means 1 stops and the material movement stops during the laminating process, the pressing roller which is in contact with the material surface also has a low pressure. Stop against the pressure of the air supply means 6.

Alternatively, the torque limiter provided at the connecting portion between the press roller 7 and the rotating shaft is operated to release the connection between the press rollers 7 and 3, whereby the rotational force to the press roller 7 is eliminated.

[0043]

According to the present invention as described above, the covering sheet itself is given by continuously heating the contact outer peripheral surface to the pressing roller for pressing the base material and the covering sheet. Well warmed and familiar with the shape of the substrate,
By activating the adhesive well, a high-quality sticking treatment can be performed.

Further, since the pressing roller is driven to rotate by a driving force lower than the transfer force of the material by the transfer means, the material is not excessively forcibly driven when the material is abnormally stopped, and the product is manufactured. No damage to materials or equipment. And so on.
